Electrical problem strikes Iran's Natanz nuclear facility

A spokesman for Iran's civilian nuclear programme says an "accident" has struck the electrical distribution grid of the country's Natanz nuclear facility, without elaborating.

Iran's Natanz nuclear site suffered a problem Sunday involving its electrical distribution grid just hours after starting up new advanced centrifuges that more quickly enrich uranium, state TV reported. It was the latest incident to strike one of Tehran's most-secured sites amid negotiations over tattered atomic accord with world powers. State TV quoted Behrouz Kamalvandi, a spokesman for Iran's civilian nuclear programme, announcing the incident.
